Expert Solution

Internal structure of heart.

The internal cavity of the heart is divided into four chambers:

Right atrium.

Right ventricles.

Left atrium.

Left ventricles.

The flow of blood occurs from, Right atrium to right ventricle to left atrium, and finally to left ventricle.From left ventricles blood is supplies to all parts of the body. Oxygen-depleted blood reaches the right atrium via the coronary sinus and superior and inferior vena cava and moves from the right ventricle via the pulmonary artery towards the lungs.Oxygen enriched blood then re-enters the left atrium via 4 pulmonary veins and evacuates the left ventricle via the aorta

The heart has valves which allow blood to flow in one direction, The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves (aortic and pulmonary valve)
